I saw it on the internet, has anyone done it? How good does it work?
Cant see the point really. Ceramic nozzles arn't very dear
Most nozzles used are ceramic
Have tried it for a blast pot gun BUT you do need to get the right (older type ?) plug as most (well the daughters fiesta ones) have a hard section in the center electrode about half way through. Think older plugs would almost come a part once separated from the metal threaded part.
but carbide is better so don't bother
How long does it take to modify a spark plug?
I used to do it, takes about a minute to drill down the centre electrode. I would do a few at a time.
And very expensive :P
about 7 quid or £7 .00
Really??? I saw one that costed like 30 dollars
large ones are the 3mm ones are roughly 7 quid .my 6mm one supposed to cost £ 60 .00
Could you send me a link where I could buy it?
I cant it fell of the back of a wagon u would need a minimum of 80cfm comp to run a 6mm jet
I was talking about the 3mm one :P
oops there 17 quid not 7 http://www.ebay.co.uk/itm/TUNGSTEN-...hash=item33cc133acc:m:mgoP9LooLdOOm8BU3DC_XvQ
Ahahah yeah I was searching right now and also found those. I will probably use the spark plugs in the start and when I get more money I will try to buy the carbide one. The carbide one looks straight how does it stay "stuck" to ball valve? Shouldn't it be conical?
cut the ball valve off blast hose and fit direct in to hose using a jubilee clip and work pot from ball valve on air supply
I could also use a small hose (like 5 cm) after the ball valve and use the jubilee clip there, right?
Until I buy the the tungsten nozzle I am going to try the car spark plugs, but my "sandblast gun" is a 1/2" ball valve which has more than 10mm hole and the small hole of the spark plug is 3mm how do I evenly reduce the size (is there like any rubber piece?), I tried it without anything and the gun gets jammed with abrasive
I have a link at work for some reasonable priced ones, will dig it out tomorrow.
